Maybe "science fiction buzzwords" is a better descriptor then, because I started at antmatter and I was like "how is that 'fringe'?"

I similarly thought this was supposed to be a list meant to help you identify when someone is deploying fringe science. But in the context of the community (sciencefiction) and some of the other comments, I've realized that I think it's meant to be sample signs you could use in a story like at a lab where that kind of "science" was being done.

AFAIK all of them are fake warning signs but, as you said, some of them reference real stuff.

I didn't add any indication that they are fake because I assumed it was implied by posting in science fiction communities. If not, I will add a warning.

I would say Maxwell's Demon:

Maxwell's demon is a thought experiment that would hypothetically violate the second law of thermodynamics. It was proposed by the physicist James Clerk Maxwell in 1867. In his first letter, Maxwell referred to the entity as a "finite being" or a "being who can play a game of skill with the molecules". Lord Kelvin would later call it a "demon".

In the thought experiment, a demon controls a small massless door between two chambers of gas. As individual gas molecules (or atoms) approach the door, the demon quickly opens and closes the door to allow only fast-moving molecules to pass through in one direction, and only slow-moving molecules to pass through in the other. Because the kinetic temperature of a gas depends on the velocities of its constituent molecules, the demon's actions cause one chamber to warm up and the other to cool down. This would decrease the total entropy of the system, without applying any work, thereby violating the second law of thermodynamics.
